Configuring the device name

About this task

A device name (also called hostname) identifies a device in a network and is used in CLI view prompts. For example, if the device name is Sysname, the user view prompt is <Sysname>.

Procedure

1. Enter system view.

system-view

2. Configure the device name.

sysname sysname

By default, the device name is H3C.

Configuring the system time

About the system time

Correct system time is essential to network management and communication. Configure the system time correctly before you run the device on the network.

The device can use one of the following methods to obtain the system time:

· Uses the locally set system time, and then uses the clock signals generated by its built-in crystal oscillator to maintain the system time.

· Periodically obtains the UTC time from an NTP source, and uses the UTC time, time zone, and daylight saving time to calculate the system time. For more information about NTP, see System Management Configuration Guide.

The system time calculated by using the UTC time from a time source is more precise.

Restrictions and guidelines for configuring the system time

After you execute the clock protocol none command, the clock datetime command determines the system time, whether or not the time zone or daylight saving time has been configured.

If you configure or change the time zone or daylight saving time after the device obtains the system time, the device recalculates the system time. To view the system time, use the display clock command.

System time configuration tasks at a glance

About this task

Banners are messages that the system displays when a user logs in.

The system supports the following banners:

· Legal banner—Appears after the copyright statement. To continue login, the user must enter Y or press Enter. To quit the process, the user must enter N. Y and N are case insensitive.

· Message of the Day (MOTD) banner—Appears after the legal banner and before the login banner.

· Login banner—Appears only when password or scheme authentication is configured.

· Shell banner—Appears before the user enters user view.

The system displays the banners in the following order: legal banner, MOTD banner, login banner, and shell banner.

Banner input methods

You can configure a banner by using one of the following methods:

· Input the entire command line in a single line.

The banner cannot contain carriage returns. The entire command line, including the command keywords, the banner, and the delimiters, can have a maximum of 511 characters. The delimiters for the banner can be any printable character but must be the same. You cannot press Enter before you input the end delimiter.

For example, you can configure the shell banner "Have a nice day." as follows:

<System> system-view

[System] header shell %Have a nice day.%

· Input the command line in multiple lines.

The banner can contain carriage returns. A carriage return is counted as two characters.

To input a banner configuration command line in multiple lines, use one of the following methods:

¡ Press Enter after the final command keyword, type the banner, and end the final line with the delimiter character %. The banner plus the delimiter can have a maximum of 1999 characters.

For example, you can configure the banner "Have a nice day." as follows:

<System> system-view

[System] header shell

Please input banner content, and quit with the character '%'.

Have a nice day.%

¡ After you type the final command keyword, type any printable character as the start delimiter for the banner and press Enter. Then, type the banner and end the final line with the same delimiter. The banner plus the end delimiter can have a maximum of 1999 characters.

For example, you can configure the banner "Have a nice day." as follows:

<System> system-view

Scheduling a task

About task scheduling

You can schedule the device to automatically execute a command or a set of commands without administrative interference.

You can configure a periodic schedule or a non-periodic schedule. A non-periodic schedule is not saved to the configuration file and is lost when the device reboots. A periodic schedule is saved to the startup configuration file and is automatically executed periodically.

Restrictions and guidelines

· To assign a command (command A) to a job, you must first assign the job the command or commands for entering the view of command A.

· Make sure all commands in a schedule are compliant to the command syntax. The system does not check the syntax when you assign a command to a job.

· A schedule cannot contain any one of these commands: telnet, ftp, ssh2, and monitor process.

· A schedule does not support user interaction. If a command requires a yes or no answer, the system always assumes that a Y or Yes is entered. If a command requires a character string input, the system assumes that either the default character string (if any) or a null string is entered.

· A schedule is executed in the background, and no output (except for logs, traps, and debug information) is displayed for the schedule.
